I would try Holdem Manager myself...
You can download it and use it for 15 days for free, after that you will have to pay for a license but I still say it's the best money you will ever spend if you are serious about your poker.
You can download it here -

Or there is another program called Pokertracker in my opinion not as good but if you look around the internet you'll find these are the best two... Although I found that poker tracker wasn't so good for tracking SnG and MTT's either way here is the link for poker tracker also. They also do a trial for 30 days -

Or as ihufa suggested you can use sharkscope I think they actually have software now too, however I haven't tried it so couldn't comment.
I hope that helps a little and welcome to the site.
